Description
Technical field
The utility model relates to the cementing studying technological domain of cement paste and outer layer sleeve in cementing technology, especially a kind of for simulating the thimble assembly of cementing test.
Background technology
Both having there is high pressure in South China Sea warbler fine jade basin, also has high temperature, is one of marine three large HTHP areas, the current world.Data according to incompletely statistics, 1984 to 2011, China's South China Sea bored 25 mouthfuls of HTHP prospect pits altogether.From drilling well situation, most of well concentrates between 4000m-5000m.In completed 25 mouthfuls of wells, temperature surpasses 200 ℃, and the superhigh-temperature and-pressure well that mud balance surpasses more than 2.20sg has 4 mouthfuls.1984-2004,15 mouthfuls, South Sea hp-ht well, the operator's of China and foreign countries operation process is all extremely hard, and well cementation success rate is not high, drilling liner cementing particularly, success rate only 47%.
According to statistics, east block has 53 mouthfuls at present at exploitation gas well, wherein 44 mouthfuls with pressure, major part is that tubing and casing is with pressure, but also have table cover and skill cover with pressure, more serious: DF1-1-D4(skill cover is with pressure) and happy Dong22-1-A3Jing (skill is overlapped with pressure).Understand the mechanical mechanism losing efficacy under cement sheath subsurface environment, can instruct and formulate targetedly cementing technology measure and selecting properly later stage job parameter, particularly optimize cement sheath deformation parameter and damage parameter, thereby reach the object that improves cementing quality, prevents the cementing inefficacy of cement sheath waterpower, extend the HTHP Oil/gas Well life-span.
In well cementation, cement sheath is significant to the production safety of Oil/gas Well, life-span and oil field development benefit to the packing performance on stratum, have higher envelope alter the cement sheath of ability be safety, environmental protection develop oil reservoir, realize the maximized important foundation of exploration and development benefit.Practical production experience shows, after cement paste replaces and puts in place, CBL/VDL test shows the good well of cementing quality, in experience, follow-up creep into, drilling fluid density increase, FIT, perforation, pressure break, variations in temperature, ask product, closing well to ask after the operations such as pressure, can cause the cement plane on cement sheath and outer layer sleeve, cement sheath and stratum to produce micro chink, cause the problems such as the channelling of Oil/gas Well well head, well head annular space be with pressure.This problem causes safety, environmental protection hidden danger, has a strong impact on Productivity Construction, greatly reduces exploration and development benefit.
This problem belongs to the long-term has channeling problem after well cementation, under current technical condition, usually occurs in the HTHP Oil/gas Well of underground working complicated condition.The reason that causes wellheadpressure is mainly that down-hole formation condition changes and the stress of outer layer sleeve-cement sheath-stratum system that later stage operation causes changes, cause annular space cement sheath stress-strain to change, cement sheath has occurred to destroy loses hydraulic seal, and gases at high pressure are altered gradually and moved to well head by the microcrack interface of inefficacy cement sheath inside.
Existing simulation STRESS VARIATION causes that the device of the cementing inefficacy of well cementation exists following features:
1) the outer layer sleeve processing experimental device not using according to reality;
Experimental facilities is inconsistent with the size of actual outer layer sleeve on external diameter and wall thickness.Experimental facilities adds man-hour in design, does not have to adopt to have the outer layer sleeve of actual use external diameter and wall thickness, but according to certain ratio, dwindles in physical dimension, and these are different from actual condition;
2) cementing process with test that to alter experimentation separated;
Having there is change in the environment while being glued to analog temperature-cementing inefficacy experiment by cement sheath, specifically comprises whether the maintenance environment of cement paste is HTHP, whether when analog temperature-cementing inefficacy experiment, whether added confined pressure, cementing environment and experimental situation separate.Now equipment generally can not guarantee that cement paste can complete cementing and carry out the experiment of temperature-cementing inefficacy in same set of equipment, and this and actual condition are not inconsistent;
3) can not quantitative assessment has channeling;
In factors such as analog temperatures, change and cause the cementing inefficacy of cement sheath, cause in the process of has channeling, just qualitative reaction has channeling has or not generation, causes the amount of has channeling when the certain operating mode of quantitative testing does not change;
4) cement sheath length is less than normal;
Aspect the cement sheath length of simulation, be generally less than 50cm, length is less than normal, can not reflect the problem that actual condition exists in experiment comparatively comprehensively;
5) test the scope of altering not comprehensive;
Testing in the method for altering, what generally adopt is at cement sheath one end injecting gas, and can the other end of usining collect gas as judging whether cement sheath and outer layer sleeve produce the standard of microannulus and the cementing quality of evaluation cement sheath.Can not detect in the centre position of cement sheath short transverse and produce microannulus and the operating mode of two ends strong bonding.
6) experimental cost is high;
All scrap after once testing with internal layer outer layer sleeve, outer field artificial stratum or outer layer sleeve that cement sheath is cementing, cause experimental study high cost.
7) experiment condition parameter is lower;
Bottom-hole static temperature can not be simulated simultaneously the highest 160 ℃, formation pore pressure 6000psi, the operating mode of maximum pressure load 10000psi in sleeve pipe.
