近年来，浙江省第四系浅层天然气勘探取得了新的突破，沿海已发现４个浅层气田，并已投入开发利用，还有两处在钻井中见较强气流尚待试气。该类气田在勘探程序上大致分为４个步骤：首先应以气苗调查与沉积相研究相结合，选定预探井位；其次应用静力触探井进行预探，发现浅气藏；第三是浅层横波地震与触探井相结合，探明浅气藏类型和气田边界；最后是钻资料井（兼生产井），算准探明储量并进行试采。目前还存在一些问题，如在勘探方法上浅层横波地震要力求降低成本、录井工作量增大、试采工艺进一步完善和如何延长气井寿命等。下一步勘探中，应加强科技攻关，进一步深化浅层天然气地质理论，形成一支“上游－下游”、经营和管理一体化的浅气层专业队伍。

A NEW PROGRESS OF EXPLORING QUATERNARY SHALLOW GAS IN ZHEJIANG PROVINCE

In recent years, the Quaternary shallow Sas exploration in Zhejiang province has made a new progress. 4 Shallow gas fields were found out along t.he coast and have ben developed already. The stronger gas streams discovered while drilling are waiting for test in another two places. The progrsm of exploring these gas fields can be divided into 4 steps: The first is selecting wildcat well locations by combining gas seepage survey with alimentary facies research; The second is finding out Shallow po reservoir by pre--exploring with arctical contact wildcat well; The third is determining the type of gas reservoir and the boundary of gas field by combining shallow shear seism with contact wildcat well; The fourth is drilling .calculating proved reserves and producting. Some problems such as that the cost of shallow shear seism is high. log is difficult, production technology is incomplete and the theory of Shallow gas geology is not profound. a special troop of integratively managing shallow gas from exploration to utilization is not formed are still existing at present.
