中曼石油(603619.SH):温7井已完成全井探井試油任務 共試油5層均獲得商業油流
格隆匯8月23日丨中曼石油(603619.SH)披露新疆温宿區塊重大合同進展,公司按照合同約定支付了1.73億元,並取得了自然資源部頒發的礦產資源勘查許可證(0200001810145),勘查面積1086.264平方千米,有效期2018年6月6日至2023年6月6日。2018年4月,公司與中國石油集團東方地球物理勘探有限責任公司吐哈物探處分公司簽訂了新疆温宿區塊377平方千米的三維地震勘探合同,開始進行新疆温宿區塊三維地震採集工作。截至目前,已完成新疆温宿區塊377平方千米的三維地震野外採集工作,完成三維地震處理解釋工作,解釋成果顯示,區塊內主要目的層新近系吉迪克組和潛山震旦系構造發育,初步發現三個有利勘探區帶,其中F1斷裂帶圈閉面積35平方千米,F2斷裂帶圈閉面積20平方千米,隆起帶構造主體有利構造面積50平方千米。這三個構造帶是三維區內目前勘探的主攻方向。
公司優選F1斷裂帶温7斷背斜進行勘探工作,截至目前,已完鑽探井2口,温7井吉迪克組砂巖油層厚度33.2m,油層埋藏深度1160到1540m,温7井未鑽到潛山地層完鑽;温7-1井在新近系吉迪克組和潛山震旦系鑽遇油層厚度57.1m。温7井、温7-1井鑽探在温7斷背斜構造較高部位,初步判斷該圈閉含油麪積內平均油層厚度在50m左右。目前在該圈閉內正在鑽探温6、温8和温8-1井。
温7井已經完成全井探井試油任務。共試油5層,均獲得商業油流,累計試油103天(包括起下管柱等非放噴求產時間),累計產出原油311.6方。温7井5個試油層位單井合計日產28方/日,屬淺層單井高產油氣發現,單層日產最高13.39方/日,單層平均日產5.6方/日。
温7-1井已經完成探井試油任務。共在潛山試氣二層,發現氣層厚度20m,累計試氣38天(包括起下管柱等非放噴求產時間)。4mm油嘴求產,氣產量19,557方/日,6mm油嘴求產,氣產量34,381方/日。累計產氣247,423方。
下一步工作計劃:隨着F1斷裂帶温7斷背斜圈閉温7井、温7-1井的成功鑽探並發現淺層高產工業油流及工業氣流,公司下一步將在三個構造帶陸續部署20口左右探井和評價井,進一步擴大油氣勘探成果。
通過後續探井、評價井的實施,開展F1斷裂帶温7區塊油藏的儲量計算和經濟評價研究工作,並向國家儲量委員會上報審批。
温宿項目温7淺層油氣高產富集區塊(油氣藏埋藏深度在900-1500m左右)的重大發現展示了温宿項目良好的勘探前景,是塔里木盆地最淺的常規油氣發現之一,推動了公司向上遊產業鏈延伸,為實施勘探開發和工程服務一體化戰略奠定了基礎,對公司油氣勘探業務長遠發展產生積極影響。
