In consequent structural and deposit evolution, it tends to shape heavy oil-sealing reservoir with highly hidden nature. 在后續(xù)的構(gòu)造沉積演化中，經(jīng)埋藏而形成稠油封堵油藏，此類油藏具有較強(qiáng)的隱蔽性。
The heavy-oil reservoir in Henan Oilfield is characterized by shallow buried depth, thin oil reservoir and viscosity of crude oil. 河南稠油油藏埋藏淺，厚度薄，原油粘度高，按照當(dāng)時(shí)國內(nèi)外稠油油藏蒸汽開發(fā)篩選標(biāo)準(zhǔn)，絕大部分油藏不能投入開發(fā)。 syxb-cps.com.cn
The distribution of heat in extra-heavy oil reservoir after steam injection in Block Wa-38 of Liaohe Oilfield was analyzed by analytical method and numerical models. 利用解析解方法及數(shù)值模擬方法，對遼河油田洼38塊特稠油油藏注蒸汽開發(fā)的熱能分布進(jìn)行了分析，并對有效利用蒸汽及提高注熱效果進(jìn)行了研究。
