摘要
大庆长垣扶余、杨大城子油层在高台子、杏树岗、太东及葡萄花地区的局部井区提交了石油探明和控制储量约1×10^8t，但总体认识和勘探程度仍然较低。该区现有探井253口，通过增产改造，有52口井获工业油流。由于受增产改造、试油工艺及施工条件的影响，还有201口井未试油或已试油未获工业油流。建立一套试油产能预测方法，针对目前还未达到工业油流的井进行试油产油能力的预测，提出有潜力井的增产和试油建议使其达到工业油流，对合理圈定含油面积及探井部署都有非常重要的意义。根据试油产能流体的弹性能流动特点，建立了适合该区的水力压裂后试油产能预测方法——比尔-麦圭尔法，并对老井进行复查，认为杏树岗-高台子地区有5口井重新试油可望达到工业油流。
The submitted proved oil reserves and controlled reservoirs of Fuyu oil layer and Yangdachengzi oil layer in partial well field of Gaotaizi area, Xingshugang area, Taidong area and Putaohua area in Daqing placanticline is about 1 ~ 108 t. However, integral understanding and exploration degree of these oil layers are very poor. At present there are 253 prospecting wells with 52 obtaining commercial oil flow after stimulation treatment. The other 201 wells are not tested or tested but without commercial oil flow due to the effect of stimulation treatment, test technology and construction conditions. A forecast method for test productivity is established in this paper in view of the prediction of oil test and production capacity for wells without commercial oil flow. It is proposed the wells with potential need to obtain commercial oil flow after stimulation treatment and test, and the study is significant to the reasonable delineation of oil-bearing area and prospecting wells deployment. On the basis of the flowing characteristics of elastic energy of the oil capacity tested fluids, the forecast method for test fluids rate forecast after hydraulic fracturing in this area is established, and the method is Bearder McGuire method. The old wells are re-examined and it is thought that 5 wells in Xingshugang-Gaotaizi area have the potential to get commercial oil flow after retest.
