新疆油田分公司稳产原油千万吨的措施及建议

The Measurement and Suggestion about Stabilizing Annual Crude Production of A Ten Million Tons by Xinjiang Oilfield Company

新疆油田分公司2002年实现了生产原油千万吨的目标,这是几代石油人为之奋斗的历史性突破。准噶尔盆地具有稳产千万吨原油产量和实现更高产量目标的雄厚的油气资源基础;几代石油人又积累了开发复杂油气田的宝贵经验,使稳产千万吨原油产量有了技术保证。对不同类型的油气藏应根据其开采的不同阶段和主要矛盾采取不同的稳产措施。如砾岩油藏应分一、二、三类,尽早开展化学驱、CO2驱、N2驱、注蒸汽热驱试验,转入三次采油实现稳产。新投入开发的中低渗透砂岩油藏,应做开发早期的管理和研究,保持稳产。稠油油藏应早转蒸汽驱开采,做好汽驱的调控实现稳产。

In2002,Xinjiang Oilfield Company will reach bright target of oil production of1000×104t,which is the historical breakthrough being strived for by Xinjiang's oil men of a few generations.Junggar basin has abundant founda-tions in hydrocarbon resources for sta bilizing a ten million tons of annual oil production and realizing even higher yield;the valuable experiences from exploitation of complex oil and gas fields accumulated by the generations of oil men are also technically guarantees for them.For different types of hydrocarbon reservoirs,different stable production measure-ments should be adopted based on different development stages and principal issues.For instance,conglomerate reser-voir should be classified into one,two or three types,and allowing implementation of chemical flooding as early as possi-ble(e.g.,CO 2 flooding,N 2 flooding and steam injection thermal flooding).After these tests,conversion into tertiary oil recovery would be made in order to realize stable production.The medium and low permeability sandstone reservoirs newly put into production should be managed and studied at the early stage;the heavy oil reservoirs should be converted into steam flooding as early as possible,followed by performing regulation and control of steam drive for maintaining stable production.
