The anticipated production flow rates and economics of the well determine tubing size, which then determines the necessary size of each previous hole and tubular. Once the tubular size and setting depths are determined, the wall thickness and grade of material are then chosen by the well designer to ensure the strength is adequate for the expected loads. Material grade is also selected to ensure it is appropriate for the fluids the tubular will encounter; corrosion resistant alloys (CRA) may be required in some environments such as CO2 or H2S. Finally, tubular connections are selected based on dimensional needs, load capacity, and gas-vs-liquid sealability. This chapter discusses types of casing and tubing; OCTG manufacturing, labeling and specifications; corrosion; API casing grades; transportation and handling; storage; and running procedures. Tubing transports the oil and gas from deep in the well to the surface – the third phase of the wellbore. Oil and gas occasionally rise to the surface on their own; usually, pumps are needed to bring the fluids to the surface. Tubing naturally has a smaller diameter than casing, except for the 4 1/2-inch diameter. An outer diameter of 114.3 mm (4 1/2 inches) is considered a threshold and can be either casing or tubing. Anything smaller is called tubing, anything larger is casing. From the surface to the bottom of the well, the casing telescopes down in size – there are various types of casing depending on their purpose and diameter. The “kickoff point” is where the wellbore gradually transitions from vertical to horizontal. Thanks to horizontal drilling, deposits can be reached in a more targeted way. At the conclusion, the drill string is removed and the production casing is inserted into the wellbore and cemented into place. The well is then fractured and the tubing is installed inside the production casing. The use of tubing permits better well control because circulating fluids can kill the well; thus, workovers are simplified and their results enhanced. Flow efficiency typically is improved with the use of tubing. Furthermore, tubing is required for most artificial lift installations. Tubing with the use of a packer allows isolation of the casing from well fluids and deters corrosion damage of the casing. Multicompletions require tubing to permit individual zone production and operation. Governmental rules and regulations often require tubing in every well. Permission may be obtained for omission of tubing in special cases (tubingless completions). These special completions typically are flowing wells with relatively small casing. Tubing strings are generally in outside diameter (OD) sizes of 2 3/8 to 4 1/2 in. but may be as large as 20 in. or as small as 1.050 in. The proper selection, design, and installation of tubing string are critical parts of any well completion. Tubing strings must be sized correctly to enable the fluids to flow efficiently or to permit installation of effective artificial lift equipment. A tubing string that is too small causes large friction losses and limits production. It also may severely restrict the type and size of artificial lift equipment. A tubing string that is too large may cause heading and unstable flow, which results in loading up of the well and can complicate workovers. The planned tubing must easily fit inside the installed casing. When selecting the material, the following must be considered: Environmental conditions Projected corrosivity of the well fluids Minimum and maximum pressures and temperature Safety aspects Cost-effectiveness The tubing must be designed to meet all stresses and conditions that occur during routine operation of the well and should have an adequate margin for unusual load conditions. It must withstand the stresses caused by tension, burst, and collapse, and it must resist the corrosive action of well fluids throughout the well life. In addition, the tubing must be handled and installed so that the tubing produces the well without failure or without causing undue operating problems. жүктеу/скачать 208,78 Kb. Достарыңызбен бөлісу:
