Nā ʻokoʻa ma waena o MWD a me LWD?

Ana ʻOiai ʻo Drilling (MWD): Abreviation for "Measurement While Drilling" ma ka ʻōlelo Pelekania.
Hiki i ka mea uila MWD ke ana i ka manawa i ka wā o ka wili ʻana, ʻo ia hoʻi, i ka wā ʻaʻole i hoʻōki ʻia ka wili ʻana, hoʻouna ka mea hoʻoheheʻe pulu lepo i ka ʻikepili i ana ʻia e ka ʻimi downhole i ka ʻili, a hōʻiliʻili ka ʻōnaehana kamepiula a hana i ka luawai manawa maoli. nā palena. A me nā palena hoʻokumu. Hiki i ka MWD ke ana i ka angle inclination, azimuth angle, tool face angle a me ka ikaika gamma kūlohelohe o ka hoʻokumu ʻana i ka wā o ke kaʻina hana wili, a hāʻawi i nā ʻāpana wellbore kūpono a me ka ʻikepili loiloi hoʻokumu no ka wili ʻana i nā luawai nui a me nā luawai ākea. He mea pono pono keia mea hana no ka hooikaika ana i ka holo wili ana a me ka hooiaio ana i ka maikai o ka wili ana ma na hana wili luawai kuhikuhi.

ʻO ka hoʻopaʻa ʻana i ka wā e ʻeli ana (LWD): ka pōkole no "Log While Drilling" ma ka ʻōlelo Pelekania.
ʻO ka mua ke ana resistivity, a laila ka neutron, density, etc. Aia ka ʻokoʻa i nā ʻāpana e loaʻa ai.
ʻO ka MWD ka nui o ke ana ʻana i ka wā e wili ana. E ana i ka azimuth o ka luawai, ka inclination o ka punawai, ke alo o ka mea hana (ka ikaika magnet, ka umekaumaha), a me ka wili alakai; LWD ana i ka punawai azimuth, pono inclination, a me ka mea paahana maka, a me ke ana resistivity, maoli gamma, pono puʻe, porosity, Density, etc., hiki ke pani i ka logging wireline.

ʻO nā palena o ka mea hoʻoili hōʻailona downhole e lilo i pulses a i ʻole nā ​​nalu kaomi, i hoʻouna ʻia i ka lepo ma o ka wai wili i loko o ka paipu drill ma ke ʻano he alakaʻi, a komo i ka ʻāpana honua o ka ʻōnaehana. Ma ka ʻaoʻao o ka ʻāina, hoʻokomo pinepine ʻia ka mea hōʻailona ma luna o ka riser i nā ʻāpana i nā hōʻailona uila a hoʻouna iā lākou i ke kamepiula ma o ke kelepona no ka kānana, decoding, hōʻike a me ka hoʻopaʻa ʻana. I kēia manawa, ʻelua ʻōnaehana hoʻoili hōʻailona i hoʻohana maʻamau, ʻo kekahi ʻano pulse a ʻo kekahi ʻano hawewe mau. Hoʻokaʻawale ʻia ke ʻano pulse i ka puʻuwai maikaʻi a me ka puʻuwai puʻuwai maikaʻi ʻole. Ke hoʻohana nei ka ʻōnaehana puʻupuʻu puʻuwai maikaʻi i kahi plunger e ālai koke i ke kahawai wai wili, me ka piʻi koke ʻana o ka piʻi piʻi a piʻi ka piko; Hoʻohana ka ʻōnaehana puʻupuʻu puʻe ʻino i ka pahu hoʻomaha e wehe koke e hoʻokahe i ka wai wili i ka annular space, e hoʻoulu ai i ka piʻi ʻana. Hoʻohana ka ʻōnaehana nalu hoʻomau i kahi pūʻulu o nā stators slotted, rotors, a me ka wai wili e hana i kahi nalu haʻahaʻa haʻahaʻa o kahi alapine i ka wā e hele ai, a lawe ʻia ka hōʻailona i ka honua me ka hoʻohana ʻana i kēia nalu ma ke ʻano he mea lawe. I ka hoʻohana ʻana i nā hāmeʻa MWD ʻano pulse e ana, e hoʻopau maʻamau i ka pamu a hoʻōki i ka turntable. I ka hoʻohana ʻana i ke ʻano hawewe mauMea hana MWD, hiki ke hana mau ke ana me ka hana wili me ka hooki ole i ka hana wili. ʻOi aku ka kiʻekiʻe o ke alapine o ka nalu hoʻomau ma mua o nā pulse maikaʻi a maikaʻi ʻole.

ʻO ka ʻōlelo maʻamau, ʻo ka ʻokoʻa ma waena o nā mea ʻelua ʻo ia ka LWD ʻoi aku ka laulā ma mua o MWD. ʻO ka hoʻohana maʻamau o MWD he probe + battery + pulse + battery + gamma, a ʻo ka LWD maʻamau he probe +pākaukau + pulse + pākaukau ++ gamma + resistivity.

Hoʻohana ka MMRO gyro inclinometer i ka ʻenehana hou o Vigor - solid-state

gyroscope a me MEMS accelerometer. ʻO ia kahi inclinometer multi-point me ka hana ʻākau ʻimi ponoʻī. Loaʻa i ka mea hana nā mea maikaʻi o ka liʻiliʻi liʻiliʻi, ka hopena o ka hopena, ke kūpaʻa wela kiʻekiʻe, a me ka pololei o ke ana ʻana. Hoʻohana nui ʻia no ka trajectory maikaʻi, ka hoʻonohonoho ʻana i ka puka aniani, ka hoʻonohonoho pono cluster a me ka perforation kuhikuhi, etc.
