【摘要】：A油田該區(qū)塊含油面積N1km~2,探明未動用地質(zhì)儲量N2×104t。該區(qū)塊共有井?dāng)?shù)150口,其中試油井30口,其中有15口獲工業(yè)油流,3口獲低產(chǎn)油流,12口井試油產(chǎn)水。顯示具有良好的產(chǎn)油前景,但區(qū)塊儲層發(fā)育薄差,試油井產(chǎn)量變化較大,油水關(guān)系復(fù)雜,而且本區(qū)同時存在二維地震資料和三維地震資料,因此為落實研究區(qū)構(gòu)造、儲層特征及油水分布規(guī)律開展地質(zhì)特征再認識研究,在此基礎(chǔ)上對合理開發(fā)方式進行研究。工區(qū)北部總體呈西北高東南低的構(gòu)造格局,斷裂較為發(fā)育,展布方向多以南北向、北北西向為主,形成的斷階帶將工區(qū)北部切割為2個相對獨立的斷塊。整體上工區(qū)北部油藏類型主要為巖性及斷層-巖性油藏,油水界面不統(tǒng)一,整體上含油層系主要分布在構(gòu)造較高部位,構(gòu)造低部位油水同層發(fā)育。工區(qū)南部油藏類型為巖性油藏,油層、差油層以及油水同層均有發(fā)育,受巖性控制影響,局部地區(qū)PI2層出現(xiàn)水夾層現(xiàn)象。在以上研究成果的基礎(chǔ)上進行了有利區(qū)預(yù)測,在未探明儲量區(qū)優(yōu)選出有利含油區(qū)。對水平井開發(fā)的可行性進行研究,確定PI2、PI4層為水平井開發(fā)目的層,水平井段為700m最優(yōu),與裂縫方向平行開發(fā)效果最好。進行水平井射孔位置研究,得出采用根端和趾端避射方案,避射程度采用兩端各130m避射較為合理。通過井網(wǎng)密度計算,經(jīng)濟極限井距為247m;通過井距優(yōu)化,合理井距為300m;直井部署區(qū)選用正方形五點井網(wǎng),井距為300m、排距150m;水平井部署區(qū)井型選用直注平采,同時并采用超前注水的開發(fā)方式進行開采。
[Abstract]:The oil-bearing area N _ 1km ~ (2) of this block in A Oilfield is 2, and the proven unproduced geological reserves N _ 2 脳 10 ~ (4) t. There are 150 wells in this block, of which 30 are test wells, of which 15 are industrial oil flows, 3 are low-yield oil flows, and 12 are oil test wells. The results show that there is a good prospect of oil production, but the reservoir development in the block is poor, the production of test wells varies greatly, the oil-water relationship is complex, and there are 2-D seismic data and 3D seismic data in this area, so in order to implement the structure of the study area, The reservoir characteristics and oil-water distribution law are studied on the basis of which the reasonable development mode is studied. In the northern part of the work area, there is a structural pattern of high, southeast and low in the northwest, and the faults are relatively developed, and the distribution direction is mainly from the north to the north, and the fault terrace is formed, which cuts the northern part of the work area into two relatively independent fault blocks. The reservoir types in the northern part of the whole area are mainly lithology and fault-lithologic reservoir, the oil-water interface is not uniform, the whole oil-bearing layer is mainly distributed in the higher part of the structure, and the oil-water layer is developed in the low part of the structure. The types of reservoirs in the southern part of the area are lithologic reservoirs, oil layers, differential reservoirs and the same oil and water layers, which are controlled by lithology, and water intercalation occurs in local PI2 layers. Based on the above research results, the favorable zone is predicted and the favorable oil bearing area is selected from the unproved reserve area. The feasibility of horizontal well development is studied. It is determined that PI2,PI4 layer is the target layer for horizontal well development, and the horizontal well section is 700m optimal, and parallel to fracture direction is the best. By studying the perforation position of horizontal well, it is concluded that it is more reasonable to adopt the method of avoiding fire at the root end and the toe end, and the degree of avoidance is 130m at both ends. By calculating the density of well pattern, the economic limit well spacing is 247m, the reasonable well spacing is 300m through well spacing optimization, the square five-spot well pattern is used in the deployment area of vertical wells, the well spacing is 300m, and the spacing is 150m. In horizontal well deployment area, straight injection and horizontal production are selected, and advanced water injection is adopted for exploitation.
